We are working on a flash like animation editor. Here you have a small video teaser about how it will look like. Note that development is in progress. Basic features like timeline, keyframes and interpolation is ready, but editor is missing copying and dragging keyframes, exporting movie and fixing some bugs.
Video shows how to create a map and initiate movie object. There are parallax background consisting of 4 layers and character object. The interesting part is that there are no sprite animation for character but instead various body parts are moved with tweens.
Animation editor is not implemented in MightyEditor yet but you can play around unfinished version on 8080 port.
